[0030] The present invention will be further described below in conjunction with the accompanying drawings:
[0031] like Figure 1-3 As shown, the present invention is a thermal insulation method for a mine slope road, comprising the following steps:
[0032] Step 1, introducing outdoor air into the preheating device for preheating;
[0033] In step 2, the preheated air enters the heating device for heating, and the heated hot air is mixed with the high-temperature steam introduced in the heating device to form a hot air of 51°C-57°C;
[0034] In step 3, the 51°C-57°C hot air heated and mixed by the heating device is sent into the air outlet device, and then leads to the mine slope road through the air outlet device;
[0035] Step 4: The hot air entering the slope road of the mine by the air outlet device is fully mixed with the cold air entering the slope road by negative pressure, and the hot air with the mixed air temperature ≥15°C is obtained.
[0036] The preheating d...
